WHEELS TO FIT ALL OF OUR CARTS VERMONT CARTS! People ask: What is the difference between a semi-pneumatic wheel and a pneumatic wheel. Well, the semi-pneumatic wheel has a hard rubber tire with a hollow core and does not need to be filled with air. The pneumatic wheel is like a bicycle tire where there is a tube which requires air. The pneumatic wheel handles better over rough terrain, however, it will need to be replenished with air from time to time.
